I am having an issue with an event calendar. When the event is a one day event and has only a start date (no end date), the event does not display and the next event in line repeats. Can anyone explain what I can change in the code to fix the issue.

EventLandingPage.ss

<% if UpcomingEvents(4) %>
			<h3><a href="events"><span>view all</span></a>Upcoming Events</h3>
			<% control UpcomingEvents(4) %>
				<div class="news-module">
					<% if EventURL %><a href="$EventURL" class="logo"><% end_if %>
						<% if EventImage %>$EventImage<% end_if %>
					<% if EventURL %></a><% end_if %>
					<p>
						<span class="date">
						<% if EventEndDate %>
						$EventStartDate.MonthAndDay -
						<% else %>
						$EventStartDate.Complete
						<% end_if %>
						<% if EventEndDate %>$EventEndDate.Complete<% end_if %>
						</span><br/>
						<% if EventURL %><a href="$EventURL"><% end_if %><strong>$EventName</strong><% if EventURL %></a><% end_if %>
						<% if EventDescription %><br/>$EventDescription<% end_if %>
						<% if EventCity %><br/>$EventCity<% end_if %>
					</p>
					<div class="clear"></div>
				</div>
			<% end_control %>
		<% else %>
			<p>There are currently no events scheduled.</p>
		<% end_if %>

EventPage.ss

<% if Events %>
		<h3>Upcoming Events</h3>
		<ul>
			<% control Events %>
			<li>
				<% if EventURL %><a href="$EventURL" target="_blank"><% end_if %><% if EventImage %>$EventImage.SetWidth(100)<% end_if %> <h4>$EventName</h4><% if EventURL %></a><% end_if %><br />
				$EventStartDate.Standard<% if EventEndDate %> - $EventEndDate.Standard<% end_if %> <br />
				<% if Location %>
				by <strong>$Location</strong><br />
				<% end_if %>
				<% if City %>
				$City
				<% end_if %>
				<% if EventDescription %>
				$EventDescription
				<% end_if %>
			</li>
			<% end_control %>
		</ul>
		<% end_if %>
